Removes single window assumptions from `flutter_test` #121549

pdblasi-google · 2023-02-27T22:00:05Z

Adds TestFlutterView to wrap FlutterView and allow modification of properties for testing
Updates TestPlatformDispatcher to wrap its views in TestFlutterViews when they are changed
Adds viewOf to WidgetController for finding a TestFlutterView related to the results of a Finder
Exposes platformDispatcher and implicitView from WidgetController (and WidgetTester)
- This is so the related viewOf method, which uses the Finder API, will be in a consistent place with these methods and other Finder APIs

Resolves #117481

Oh, one more thing: I seemed to recall that we considered whether we should auto-reset the testvalues on the TestFlutterView (and ideally TestFlutterPlatformDispatcher) between tests. Did you decide against doing that or did I just miss it?

I plan on doing that work in a separate PR. I want to do a revamp of how the testWidgets method does its setup and teardown to make it more consistent with the regular test framework. I'm not sure what to do with it in the meantime, but I'm leaning towards leaving it be and letting users forget to reset and solve the resetting issues themselves as needed.

I believe the accidental deletion of this getter caused b/272195069.
